| Many Internet2 applications require QoS | ||
| Despite years of IntServ/RSVP work, scalable & interoperable QoS is not here! | ||
| Internet2 QoS Working Group wrestled with this and... | ||
| Launched QBone initiative to: | ||
| Build a QoS testbed and iterate as we learn | ||
| Balance networking research with providing a service | ||
| Build upon IETF DiffServ work | ||
| Support intradomain & interdomain deployment | ||
| Q: What services do tomorrow’s applications need? | |
| A: There are really a broad range of needs | |
| Need better understanding through experience |
“Typical” Internet2 Performance
| IETF “Diff” + QBone “Serv” | |||
| Diff: Expedited Forwarding (EF) (RFC 2598) | |||
| Serv: QBone Premium Service (QPS) | |||
| Contract: leased line emulation at a specified peak rate | |||
| Near-zero loss | |||
| Low, bounded jitter | |||
| Reservation Setup Protocol | |||
| Phase0: long-lived, manual setup, campus-to-campus extent | |||
| Phase1: more dynamic, automatic setup, flexible extent | |||
| QBone Measurement Architecture | |||
| Uniform collection of QoS metrics | |||
| Uniform dissemination interface | |||
| QBone architecture (v1.0) finalized | |
| QBone BB Advisory Council (QBBAC) draft recommendations on web site | |
| Interdomain QPS demonstrated (nM demo) | |
| UCAID participation in DOE/NGI testbed (instrumentation, consultation) | |
| QCon router interoperability event | |
| BBop bandwidth broker operability event | |
| Chartered to recommend inter-BB signaling experiment | ||
| Numerous R&E and corporate partners | ||
| 6 proto-BBs recently tested at BBop: | ||
| Merit | ||
| U. Kansas | ||
| Siemens | ||
| Requirements/protocol draft on web site | ||
| Converging on recommendation; top contenders: | ||
| Lightweight, flexible setup protocol | ||
| Int-over-Diff | ||
| The Plan: | |||
| Abilene aggressively implementing QBone architecture | |||
| The Status: | |||
| Testing GSR edge card functionality (CAR) | |||
| Deploying new GSR core cards (MDRR) | |||
| Pursuing QBone peerings with ESNet, Dante | |||
| Phased rollout starting “real soon” | |||
| The Team: | |||
| UCAID | |||
| Indiana U. | |||
| I-TEC | |||
| North Carolina | |||
| Ohio | |||
| Abilene QBone deployment (Fall/Winter) | |
| Final QBBAC recommendations (r.s.n.) | |
| Second Internet2 Joint Applications/Engineering QoS Workshop: “QBone: Early Experiences and the Road Ahead” (Feb 9-10) | |
